COAL-DERRICK FOR VESSELS.

SPECIFICATION forming part of Letters Patent N o. 714,465, datedNovember 25, 1902.

Application led (l'nly 15,1902. SerielNo.115,639. (No model.)

To @ZZ whom t may concern.-

l Be it known that we, OTTo ELIASEN and PETER C. NELSON, citizens of theUnited States, residing at Brooklyn, in the county of Kings andState ofNew York, have invented :certain new and useful Improvements in CoalpDerricks for Vessels, of which the following is a full and completespecification, such as .i will enable those skilled in the art to whichitappertains to make and use the same.

The object of this invention is to provide an improved apparatus orderrick particularly designed for use in loading vessels with theircoal-supply or which may be used for y and other objects in view theinvention consists of an apparatus of the class specified other andsimilar purposes; andwith these constructed as hereinafter described andclaimed.

The invention is fully disclosed in the following speciication, of whichthe accompaf nying drawings form a part, in which the separate parts ofour improvement are designated by suitable reference characters in eachof the views, and in which- Figure lis a side elevation of our improvedapparatus and showing a transverse section l of part of the hull of avessel; Fig. 2, a plan fsb view of part of the apparatus which weemploy; Fig. 3, a bottom plan view thereof,and Fig. 4 a sectional sideelevation of that part of the apparatus shown in Figs. 2 and 3.

\ In the drawings forming part of this speciflcation we have shown at aa vertical section .35

of a part of the side. of the hull of a vessel and at d2 a similarsection of a part of the deck of a vessel, and in` the practice of our`invention we provide an upright support b, one

a end of which in the form of construction provided, or it may be anindependent support connected with the deck or decks of the ves- 1` lsel in any desired manner.

Connected with the upright support h is a boom c, and in the form ofconstruction shown the boom c is connected with the upright supy port bby means of a band c2, which is free to turn on said support and towhich the boom c is pivoted at c3, and the said boom is thus connectedwith said support in such a nuanner that the front end of said boom maybe swung in a horizontal plane or moved in a vertical plane, as will bereadily understood, and any device for connecting said boom with thesupport b may be employed that will accomplish the above result.

Mounted on the boom c is a traveler d, which is oblongin form andbox-shaped in cross-section and which consists of side members d2,connected by transverse rods d3 at the top and bottom thereof and byratransverse top plate b4'at the front end thereof; lbut the vframework ofthe traveler cl may be made in any desired manner.

Mounted in the top portion of the traveler d are two rollers e, whichare mounted on transverse shafts c2, and the rollers e bear upon theboom c and support the traveler d, and in the bottom portion of saidtraveler beneath the boom c is a pulley-wheelf, mounted on the shaft f2.The front end of the traveler d is provided with a downwardly andforwardly directed extension d5, in which is piv.- oted at d a lever g,the rear end of Whichis much wider than the front end and provided witha vertical groove g2, in the side walls of which are formed transverserecesses g8. The front end of the lever g is providedwith upwardlydirected members g4, in which is mounted an antifriction-roller g5,whichin certain positions of the lever gis adapted to bear on the bottom ofthe boom c.

The boom c is provided at its outenor front end with an upright memberc4, which in the the end of the boom and block-shaped in form, and theend of which adjacent to the body of the boom is provided with a buerc5, which limits the outward movement of the traveler d. The boom c isalso provided in its free end with a recess c6, which is adapted toreceive the antifriction-roller g5 in a certain position of the lever g,as shown in Fig. 1.1

Connected with the upright support h below the connection with saidsupport of the boom c is a pulley 71, and around this pulley is passed arope h2, which is also passed into the traveler d beneath the boom o andaround `the pulley-wheel f, and connected with the free end of this ropeat h3 is a basket, bucket, or similar device h4, and near the bucket orother device h4 the rope h2 is provided with a stop-collar or similardevice 71.5, which is secured thereto.

Connected with the front end of the boom c, as shown at t' in Fig. 1, isa rope 2, which is passed around a pulley 3 at the top of the support b,and in the form of construction shown is connected with a hook orsimilar attaching device t4, secured to the support b, and the rope t4is 4intended to be used for the purpose of raising and lowering thefront or outer end of the boom c. Connected with the front end of theboom c, as shown at k, are two guide lines or ropes 7a2, which may becarried to any desired point laterally of the support b and which areintended for use in swinging the boom c laterally or moving it from oneside to the other. In practice the end h6 of the rope h2 is connectedwith a windlass or similar device for the purpose of raising andlowering the basket or bucket h4 and for moving the traveler d on theboom c, and in Fig. l of the drawings we have also shown at m a barge orother vessel,which is supposed to contain coal, and the operation of theapparatus will be readily understood from the foregoing description whentaken in connection with the accompanying drawings and the followingstatement thereof.

It will be understood that the boom c may be raised and lowered at anytime and to any desired extent by means of the rope i2; but it will alsobe understood that this boom is not while in operation raised orlowered, the position thereof being adj usted before the operation ofloading coal is begun. In the operation of loading coal the rope h2 ismanipulated by a windlass or similar device in the usual manner, and thebasket or bucket h4 is lowered and filled with coal. The said basket orbucket is then raised by winding the rope 72,2 on the windlass, and whenthe stop or collar h5 approaches the pulley-wheelf it strikes said wheeland enters the transverse recess g3 in the adjacent end of the lever g,and the rope h2 at the same time is thrown outwardly into the verticalgroove or recess g2 in said lever, as clearly shown in Fig. 4. The stopor collar h5 operates to throw the adjacent end of the lever h2 upwardlyand the outer end of said lever downwardly into the position shown inFig. 4, and the traveler d at once moves backwardly on the boom c in thedirection of the support b, and at the limit of its backward movementthe basket or bucket h4 is lowered and the coal emptied therefrom in theusual manner. After the basket or bucket has been emptied and releasedthe windlass is unwound and the traveler d moves automatically back tothe position shown in Fig. l and the basket or bucket descends, so as tobe again illed with coal. In order to facilitate the movement of thetraveler back to the free or swinging end of the boom c, the said boom cis held in a slightly-inclined position and the traveler moves on theboom by gravity, as will be readily understood. In the position of saidtraveler shown in Fig. l the lever g also assumes the position shown insaid figure, and the antifriction-roller g5 enters the notch c6 in theend of the boom c and the traveler is locked to said boom till thebasket or bucket h4 is again raised, at which time the parts againassume the position shown in Fig. 4 and the traveler is moved backwardlyalong the boom c. It will be understood that the boom c may be swung inthree directions, and the coal may thus be deposited at any point in oron the vessel.

The sides of the carrier d are provided with slots or grooves ge, andthe lever g is provided with a pin g?, which moves in said slots orgrooves in order to limitthe movement of the lever g at any time, andparticularly to arrest said movement when the 'traveler is off of theboom, and the entire apparatus is simple in construction and operationand comparatively inexpensive and may be applied to any vessel and alsoused in other relations, and changes in and modifications of theconstruction described may be made without departing from the spirit ofour invention or sacricing its advantages.

Having fully described our invention, what we claim as new, and desireto Secure by Letters Patent, is-

1. In an apparatus of the class described, the combination with asuitable su pport, of a boom connected therewith and adapted to swingvertically and in a horizontal plane, a traveler mounted on said boomand provided in the lower side thereof with a pulley, a rope passingover said pulley and adapted to support a bucket or similar device andprovided near said bucket or similar device with a collar or stop, and alever pivoted in the bottom of the traveler and adapted to engage theend of the boom at one end, and provided at its other end with avertical recess to receive said rope, and a transverse recess to receivesaid collar or stop, substantially as shown and described.

2. In an apparatus of the class described, a traveler adapted to bemounted upon a boom and to move longitudinally thereof, said travelerbeing provided in the lower side thereof with a pulley, and a leverpivoted in the bottom of the traveler and provided at its forward endwith an upwardly-directed member, and at its rear end with avertically-arranged recess and also a transversely arranged recess,substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of the subscribing witnesses, this 14th day ofJuly, 1902.
